Honestly even 60FPS has a ton of blur my 165Hz display.
60FPS does look better on a 60Hz display however (my laptop)
But nevermind framerates - I just hope the core gameplay and mechanics of GTA6 are better. The previous GTA games have genuinely terrible gameplay with tank controls. You want good gameplay? Go play Sleeping Dogs or Watch Dogs. Your character movement, aiming - all superior to anything Rockstar has released.
RDR2 also controls like garbage. Sure, they have created a 'wonderful and engrossing world' - but if the game plays like shit, why does that matter?
The only mechanically good game I've played from Rockstar is Max Payne 3.
